Historically, scientists believed the brain processed color (chromatic) and brightness (achromatic) through entirely independent channels. Recent research, however, shows these signals are deeply "interdependent." This paper would investigate how a high-contrast black-and-white background can actually "blind" us to subtle color changes, potentially leading to new models for how the primary visual cortex (V1) manages data overload.
